水杨酸异丙酯合成路线

水杨酸异丙酯制备

水杨酸异丙酯的合成主要有以下两种方法。
(1)酸催化酯化法
由水杨酸与异丙醇在硫酸催化下酯化制得。
将一定量的水杨酸和异丙醇加入反应釜中，开动搅拌，慢慢滴加浓硫酸，同时打开反应釜夹套蒸汽阀，当温度升至87℃左右时停止搅拌。在88～98℃之间回流反应8～10h，再升温至114～118℃，回流反应6～8h。反应终点以控制水杨酸转化率为准。停止加热，冷却，将上层酯抽入水洗釜，用饱和碱水中和至pH=8～9，停止搅拌，静置45min后分出水层，酯层加入等体积水洗涤、静置分层，除去废水层后即得到水杨酸异丙酯。
(2)酰化酯化法
将水杨酸用氯化亚砜催化酰氯化后，再用异丙醇酯化制得。
在反应釜中依次加入一定量的水杨酸、催化剂和氯化亚砜，在负压下升温20min后开动搅拌，慢慢升温，至釜温达到30℃后保温1.5h，继续升温到40℃开始滴加异丙醇。加毕，在(50±2)℃条件下保温1.5h。反应完毕后，抽至水洗釜水洗、碱洗及二次水洗，静置分层，即得到水杨酸异丙酯。
